We have reviewed the renormalization procedure used in the unitarized coupled-channel model of Romanets et al. (Phys Rev D 85:114032, 2012), and its impact in the [Formula: see text], [Formula: see text], and [Formula: see text] sector, where five [Formula: see text] states have been recently observed by the LHCb Collaboration. The meson-baryon interactions used in the model are consistent with both chiral and heavy-quark spin symmetries, and lead to a successful description of the observed lowest-lying odd parity resonances [Formula: see text] and [Formula: see text], and [Formula: see text] and [Formula: see text] resonances. We show that some (probably at least three) of the states observed by LHCb will also have odd parity and [Formula: see text] or [Formula: see text], belonging two of them to the same [Formula: see text] HQSS multiplets as the latter charmed and beauty [Formula: see text] baryons.
我们回顾了罗曼内茨等人（《物理评论D》85:114032，2012年）的幺正耦合通道模型中使用的重整化程序，及其在[公式：见正文]、[公式：见正文]和[公式：见正文]扇区中的影响，大型强子对撞机底夸克合作组最近在该扇区观测到了五个[公式：见正文]态。该模型中使用的介子 - 重子相互作用与手征和重夸克自旋对称性均一致，并成功描述了观测到的最低激发态奇宇称共振[公式：见正文]和[公式：见正文]，以及[公式：见正文]和[公式：见正文]共振。我们表明，大型强子对撞机底夸克合作组观测到的一些（可能至少三个）态也将具有奇宇称且[公式：见正文]或[公式：见正文]，其中两个与后述的粲夸克和底夸克[公式：见正文]重子属于同一[公式：见正文]重夸克自旋对称性多重态。
